Nantong — Shipbuilding Industry

Nantong Shipbuilding Industry Overview

Nantong, located on the northern bank of the Yangtze River opposite Shanghai, has developed into one of China's most important shipbuilding and marine engineering centers. The city hosts over 300 shipbuilding and marine equipment manufacturing enterprises, including major state-owned shipyards and specialized marine component manufacturers. Nantong's shipbuilding cluster ranks among China's top three in deadweight tonnage (DWT) capacity.

COSCO Shipping Heavy Industry's Nantong shipyard is the anchor enterprise. The shipyard specializes in building bulk carriers, container ships, oil tankers, and specialized vessels including chemical tankers and LNG carriers. Other major shipyards include Nantong COSCO KHI Ship Engineering (a joint venture with Japan's Kawasaki Heavy Industries) and Nantong Rainbow Offshore & Engineering Supplies.

Offshore platform component manufacturing is a distinctive strength of Nantong's marine industry. The city's shipyards build jacket platforms, topside modules, floating production storage and offloading (FPSO) vessels, and offshore wind turbine installation vessels. The transition to offshore wind energy has driven significant demand for specialized vessels and components.

Marine equipment manufacturing encompasses a wide range of specialized products. The city produces marine diesel engines through licensed partnerships with MAN, Wärtsilä, and Mitsubishi; marine propulsion systems including controllable pitch propellers and azimuth thrusters; deck machinery including winches and cranes; and ship electrical systems including switchboards and automation systems.

The shipbuilding supply chain in Nantong benefits from exceptional Yangtze River logistics. The deep-water Yangtze river channel enables direct access to the East China Sea for completed vessels and large components. The Nantong Shipbuilding Industry Park provides dedicated waterfront facilities, heavy-load quays, and shared steel processing and coating facilities.

For international shipping companies and offshore operators, Nantong offers high-capacity shipbuilding capabilities, competitive pricing, and proximity to Shanghai. Many shipbuilders hold certifications from major classification societies including Lloyd's Register, DNV, Bureau Veritas, and ABS. Maritime training programs provide a consistent pipeline of skilled welders, fitters, and marine engineers.
